i searched for a previous forum post but none came came up so if its out there shoot me a link. My storage unit does not have access to power to charge on board batteries. Was asking if anyone had information on how to set up a solar unit to charge the on board batteries so i don't have to remove them to charge. don't know if its possible so any information is appreciated. should have also said my HOA wont allow me to park the boat and charge it.

thanks

To get enough amps to charge a battery in a reasonable length of time, the whole storage unit roof will need to be covered with solar cells.

I have installed solar units to more than boats than I can remember in Corpus Christi. They work great! The main ones being ones that are center console with a tower. At Coastal Offshore, we generally would install 2 solar panels on top of the tower, wired down through the post and they were hard wired in and were the were always charging, unless you turned them off by an installed switch. Most of our clients were charging 2-4 batteries for starting and trolling. You can get these in 5 and 20 watt. Most generally 10 watt in sufficient since your not using the boat everyday, it will be trickle charging 90% of the time. The panels were general 18x24 inches. They will not charge your battery in a hours, however, they will slow charge them and keep them maintained over an extended amount of time, which is what your after in a storage type setting. You don't have to have them permanently mounted. I have seen a lot of boats in storage where they had the solar units mounted on a board of some type where they could disconnect them when in in use. Just remember that they must have access to all daytime sunlight, thus the reason we mounted them to the towers of the center console boats. Good luck and if you have any questions feel free to contact me at my number below. We are only open Tue-Sat during the fall.

Google solar charging marine batteries and you can find multiple choices of applications and find one that is right for your purpose.

If you do the math, even a 10 or 20 watt solar charger system is not going to reliably charge your typical bass boat's 3 or 4 deeply discharged batteries back up by a following weekend and even with several more days of short winter days and cloud cover charging time, would prove unreliable. If you dayfish both weekend days nearby, you are likely over-discharging and damaging the batteries unless you are using two sets and changing them out.

Using spillproof AGMs with a good handle, converting all electrical connections to ring terminals for the threaded posts performing the charging at home is an option.
